Description

Die Erfindung betrifft einen Locher mit einem auf einer Unterlage aufstellbaren Unterteil, mindestens zwei am Unterteil in ihrem gegenseitigen Abstand verstellbar angeordneten, je eine Lochmatrize, einen Einschubschlitz und einen Lochstempel aufweisenden Locheinheiten, einem am Unterteil schwenkbar gelagerten oder verschiebbar geführten, vorzugsweise als Druckhebel ausgebildeten Druckorgan zum Verschieben der Lochstempel, und einer im Bereich vor den Einschubschlitzen der Locheinheiten sich über die Einschublänge des Unterteils erstreckenden Skala für die Einstellung der Lochabstände zwischen den Locheinheiten.The invention relates to a punch with one on one Base erectable base, at least two am Lower part adjustable in their mutual distance arranged, each a perforated die, an insertion slot and punch units having a punch, a pivotally mounted or slidable on the lower part guided, preferably designed as a pressure lever Pressure element for moving the punch, and one in the area in front of the insertion slots of the hole units the insertion length of the lower part extending scale for setting the hole spacing between the punch units.

Mehrfachlocher mit verstellbaren Locheinheiten dieser Art sind üblicherweise mit feststehenden oder auswechselbaren Skalen ausgerüstet (GB-A-799616). Größtenteils handelt es sich dabei um Millimeter- oder Zoll-Einteilungen, anhand derer für verschiedene Ordner- oder Ringbucheinlagen die Abstände zwischen den Locheinheiten errechnet werden müssen. Einfacher wäre es, wenn die Abstände für die verschiedenen Ringbuchtypen unmittelbar auf der Skala angegeben wären. Wegen der Vielzahl der in der Praxis vorkommenden Ringbuchtypen mit unterschiedlichen Lochabständen ist dies bei den herkömmlichen Mehrfachlochern aus Gründen der Übersichtlichkeit der Markierungen aber nicht ohne weiteres möglich. Die bereits vorgeschlagene Auswechslung der Skalen führt andererseits zu unerwünschten Umrüstzeiten, ganz abgesehen davon, daß die augenblicklich nicht eingesetzten Skalen verlorengehen können.Multiple punches with adjustable punching units Type are usually fixed or interchangeable Scales equipped (GB-A-799616). Mostly are these millimeter or inch graduations, based on those for different folder or ring binder inserts the distances between the punch units have to be calculated. It would be easier if the Clearances for the different ring binder types immediately would be indicated on the scale. Because of the multitude of the ring binder types that occur in practice with different Hole spacing is the case with conventional ones Multiple holes for reasons of clarity the markings are not possible without further ado. The already proposed replacement of the scales leads on the other hand, at undesirable changeover times, not to mention of the fact that the currently not used Scales can get lost.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, den Mehrfachlocher der eingangs angegebenen Art dahingehend zu verbessern, daß die Einstellung verschiedener Lochabstände zwischen den Locheinheiten durch eine übersichtliche Skalierung unterschiedlicher vorgegebener Lochraster vereinfacht wird.Proceeding from this, the invention is based on the object the multiple hole punch of the type specified at the beginning to improve that hiring different Hole spacing between the punch units through a clear scaling of different predetermined hole pattern is simplified.

Die Erfindung geht von der Erkenntnis aus, daß ein Mehrfachlocher der genannten Art für eine Vielzahl unterschiedlicher Lochabstände einsetzbar ist und daß es deshalb vorteilhaft ist, wenn die hierfür erforderlichen Skalen übersichtlich und unverlierbar unmittelbar am Locher angeordnet sind. Um dies zu erreichen, wird gemäß der Erfindung vorgeschlagen, daß im Unterteil im Bereich vor den Einschubschlitzen der Locheinheiten eine sich über die Einschublänge des Unterteils erstreckende, nach oben offene Aussparung angeordnet ist, und daß in der Aussparung ein sich um seine Längsachse drehbarer Skalenträger angeordnet ist, der mehrere, in verschiedenen Drehlagen nach oben weisende, in der Aussparung sichtbar werdende Skalen trägt.The invention is based on the knowledge that a Multiple holes of the type mentioned for a variety of different Hole spacing can be used and that it is therefore advantageous if the necessary for this Scales clear and immediately captive are arranged on the punch. To achieve this, proposed according to the invention that in the lower part in Area in front of the insertion slots of the punch units extending over the insertion length of the lower part, upward open recess is arranged, and that in the recess a rotatable around its longitudinal axis Scale carrier is arranged, the several, in different Rotational positions facing upwards in the recess visible scales.

Gemäß einer bevorzugten Ausgestaltung der Erfindung steht der Skalenträger mit seiner jeweils nach oben weisenden Skala über die Aussparung des Unterteils über und kann in den den verschiedenen Skalen zugeordneten vorgegebenen Drehstellungen am Unterteil arretiert oder eingerastet werden. Der Skalenträger hat vorteilhafterweise die Gestalt eines Rundstabs, kann jedoch auch als Mehrkantstab oder als Flachstab ausgebildet sein.According to a preferred embodiment of the invention is the scale carrier with its upwards pointing scale over the recess of the lower part about and can be assigned in the various scales predetermined rotational positions locked on the lower part or snapped into place. The scale carrier has advantageously the shape of a round rod, can however also designed as a polygonal rod or as a flat rod be.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, daß an den Enden des Skalenträgers achszentral überstehende Lagerzapfen angeordnet, vorzugsweise angeformt sind, die in drehfest mit dem Unterteil verbundene Zapfenlager eingreifen. Es ist dabei zweckmäßig, mindestens eines der Zapfenlager als lösbar am Unterteil befestigbare, vorzugsweise einrastbare Lagerhülse auszubilden. Zwischen mindestens einem der Zapfenlager und dem Skalenträger sind vorteilhafterweise federunterstützte Rastmittel zur Arretierung des Skalenträgers in den vorgegebenen Drehstellungen angeordnet. Zu diesem Zweck kann an der vorzugsweise aus Kunststoff bestehenden Lagerhülse eine biegeelastische Federzunge angeformt werden, die einen in über den Umfang des Skalenträgers verteilt angeordnete Rastvertiefungen radial einrastenden Rastnocken aufweist. Um trotz der bestehenden Maßtoleranzen ein sicheres Einrasten zu gewährleisten, werden die Rastvertiefungen vorteilhafterweise in Achsrichtung des Skalenträgers langgestreckt ausgebildet.Another advantageous embodiment of the invention provides that axially central at the ends of the scale carrier protruding journal arranged, preferably are integrally formed, which are non-rotatably connected to the lower part Intervene pin bearing. It is advisable at least one of the journal bearings as releasable on Lower part attachable, preferably snap-in bearing sleeve to train. Between at least one of the journal bearings and the scale carrier are advantageous spring-supported locking means for locking the scale carrier arranged in the predetermined rotational positions. For this purpose, preferably made of plastic existing bearing sleeve a flexible spring tongue be molded into one over the scope of the scale carrier arranged arranged recesses has radially engaging locking cams. To despite the to ensure existing dimensional tolerances are securely engaged, the recesses are advantageously elongated in the axial direction of the scale carrier educated.

Als Alternative hierzu können die Rastmittel durch eine in einer exzentrischen achsparallelen Aussparung des Zapfenlagers, vorzugsweise der Lagerhülse, angeordnete, federunterstützte Rastkugel sowie eine Anzahl über die dem betreffenden Zapfenlager zugewandte Stirnfläche des Skalenträgers im Radialabstand der Rastkugel umfangsverteilt angeordnete Rastvertiefungen gebildet sein.As an alternative to this, the locking means can be replaced by a in an eccentric axis-parallel recess of the Journal bearing, preferably the bearing sleeve, spring-supported detent ball and a number over the the end face of the journal in question Scale carrier circumferentially distributed in the radial distance of the locking ball arranged recesses can be formed.

Um das Drehen des Skalenträgers zu erleichtern, ist es von Vorteil, wenn einer der Lagerzapfen durch das zugehörige Zapfenlager, vorzugsweise durch die Lagerhülse hindurchgreift und an seinem über das Zapfenlager überstehenden Teil einen mit dem Skalenträger drehfest verbundenen, vorzugsweise angeklebten Drehknopf trägt.To make it easier to rotate the scale carrier, it is an advantage if one of the trunnions is replaced by the associated one Pin bearing, preferably through the bearing sleeve reaches through and on his protruding over the journal bearing Part of a rotatably connected to the scale carrier, preferably glued knob.

Aus herstellungstechnischen Gründen besteht der Skalenträger zweckmäßig aus längsgeteilten, einander spiegelbildlich ergänzenden und miteinander verrast-und/oder verklebbaren Stabhälften, wobei die Stabhälften zweckmäßig als gleichgestaltete Spritzgußteile aus Kunststoff ausgebildet sind.The scale carrier exists for manufacturing reasons expediently of longitudinally divided, mirror images of each other complementary and locked together and / or stickable rod halves, the rod halves being useful as identical injection molded plastic parts are trained.

Da die Papierformate trotz gleicher Lochabstände unterschiedlich sein können, ist es von Vorteil, wenn am Unterteil zusätzlich eine parallel zum Skalenträger längsverschiebbar angeordnete und in verschiedenen Verschiebestellungen einrastbare Anschlagschiene vorgesehen ist, die einen senkrecht über das Unterteil überstehenden Anschlag für eine Seitenkante des zu lochenden Schriftguts aufweist.Because the paper formats differ despite the same hole spacing it can be advantageous if on the lower part additionally one longitudinally displaceable parallel to the scale carrier arranged and in different displacement positions snap-in stop rail provided is one that projects vertically above the lower part Stop for one side edge of the hole to be punched Exhibits writing.
